Colin couldn't help but giggle a little as he realized what his moving around seemed to be doing. He stilled for a moment before leaning over to grab the chocolate. He blinked a couple times at Zach's words, arching an eyebrow. "I do?" He paused for a moment, re situating himself in Zach's lap and leaning against him before breaking off a piece of chocolate and nibbling on it quietly for a moment.
"I have you," he murmured after a moment. "I have what I want." He leaned back, breaking off another piece of chocolate and holding it up so he could easily reach it with his mouth. "Here. It's for you, if you want it."
He tried to keep himself still for a little while, but he couldn't help it. Sitting still was a really difficult thing for him to do, admittedly. He hummed softly, pressing a couple kisses to Zach's cheek. He liked Zach, and really, he didn't mind doing whatever Zach wanted. He didn't know what most of the things people did were, so he couldn't say whether he wanted to do them or not. He knew he didn't want to be hurt, but that was about all he knew.
